Without further ado, go straight to the code

function keyUp(){
         if(navigator.appName == "Microsoft Internet Explorer"){
           var keycode = event.keyCode;             
           }else{
            varkeycode = keyUp.caller.arguments[0].which;       
           }
          alert(keycode);
      }
